[Elecraft] KX1 Power Output
I hope you can read this, but do the values look reasonable, for a KX1 with the output power mod. Peak to peak (Vpp) voltages and RMS (Vrms) were taken with a high end O'scope and used to compute the Power values (Ppp and Prms). Seems the KX1 read the supply voltage about 0.4 volts low.

Re: [Elecraft] KX1 PA Transistor Availability?
Can anyone comment on a BD139-16 as a replacement for the 2SC5739?

Re: [Elecraft] KX1 ATU?
I'll mess around with it. My K2 tunes it without any problems so I thought the KX1 ATU would also.

Indeed, you might not need the tuner at all! Ron AC7AC -Original Message- My KX1 (with tuner) tunes great to a random wire or my G5RV but I can't get better than about 6.1 into my home made Buddie Pole (coax feed). I'm assuming I need a balun? Maybe like Elecraft mini 1:1 or 4:1 unit. -TAC, KC8SES __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
